SLEEVE EXTENS ION ADAPTER Filed April 1, 1966 INVENTOR. 60 17. P553451Qaigmdew United States Patent US. Cl. 214-653 1 Claim ABSTRACT OF THEDISCLOSURE A sleeve extension adapter for use with a Bartell equippedlift truck having a horizontal extensible boom and a depending pin orarticle engaging member at its outer terminal end, in which the sleeveextension adapter is a tapered bar formed of at least three cylindricalintegral sections of different diameter with the larger diameter sectionat the top. Formed in the larger diameter section is an axial closedbore of a diameter and length such as to snugly receive the dependingpin therein, there being aligned openings in the pin and the walls ofthe larger diameter bar section to receive a fastener bolt therethrough.The adapter when mounted on the pin will permit the Bartell lift truckto lift roll loads of a width less than the conventional standard widthof roll loads normally handled by the lift truck.

This invention relates to a sleeve extension adapter for use with aBartell equipped lift truck for the transport of a roll of printingpaper.

Rolls of printing paper in shipment in freight cars stand on end withtheir axes vertical, the lower end of the rolls engaging the floor ofthe freight car. A roll of printing paper is of large diameter andnormally of a standard height. There is in use what is known as aBartell equipped power operated lift truck that has a boom on a supportcarriage, and a depending pin on the boom that is inserted into theaxial sleeve or core of the roll of printing paper at its upper end.Power means pulls the pin to the support carriage and moves the rollinto a clamped engagement with a cradle carried by the support carriage.The roll of printing paper thus clamped in position can then be elevatedby a raising of the support carriage and transported by the lift truckto its selected location. Where, however, the roll of printing paper isof a width smaller than the conventional width of a roll of printingpaper, the pin which is relatively short cannot be inserted far enoughinto the axial sleeve or core of the roll, and in some cases cannot bebrought down low enough for insertion into the axial sleeve or core ofthe roll, so as to move the same into clamped seating engagement in thecradle of the carriage support.

Accordingly it is the principal object of this invention to provide anadapter for connection to the pin on a Bartell equipped truck that willfunction to provide a pin of increased length sufiicient for use withrolls of printing paper of smaller width.

Another object of this invention is to provide a rigid adapter that istapered or stepped and which is provided at its larger diameter end withan axial bore forming a sleeve adapted to receive the pin, and includingfastener means for securing the adapter to the pin.

Further objects of the invention will appear as the descriptionproceeds.

To the accomplishment of the above and related objects, my invention maybe embodied in the form illustrated in the accompanying drawings,attention being called to the fact, however, that the drawings areillustrative only, and that change may be made in the specificconstruction illustrated and described within the scope of the appendedclaim.

FIGURE 1 is a perspective view of the sleeve extension adapter.

FIGURE 2 is a longitudinal sectional view thereof taken on line 22,FIGURE 1.

FIGURE 3 is a side elevational view showing the invention applied to aBartell equipped truck.

Referring in detail to the drawings, FIGURE 3 shows at 10 a Bartellequipped lift truck designed to move printing paper rolls. The truck 10is particularly employed to move such printing paper rolls which arestacked on end on the floor of a freight car, i.e., with the axis of theprinting paper roll vertical, to a location removed from the freightcar. The Bartell equipped lift truck 10 is pro vided with asubstantially vertical frame 12 on which is suitably mounted for up anddown movement, a support carriage 14. A hydraulic ram and control system(not shown) actuates the carriage in its up and down movement.

Carried by the support carriage 14 is a forwardly extending fixedcantilever boom 16 which is hollow. Axially slidable within the boom 16is a depending pin 18, shown in dotted lines in FIGURE 3 as dependingvertically and downwardly from the boom 16. A hydraulic ram (not shown)within the boom 16 is connected to the pin 18 to move the same towardsor away from the support carriage 14. An arcuate skeleton cradle 20 isfixed to the support carriage 14 and is adapted to receive one side of aroll of printing paper.

It is to be noted that the pin 18 is short which is conventional in aBartell equipped lift truck, the short length of the pin 18 beingsufficient for insertion in the axial sleeve or core of the upstandingroll of printing paper of a normal width. Where, however, the rolls ofprinting paper are of a width considerably smaller than the normalwidth, the short length of the pin 18 cannot satisfactorily engage theaxial sleeve or core of the (smaller) roll to move the same into thecradle 20 of the support carriage 14.

Accordingly there is provided a sleeve extension adapter 26 for use withthe pin 18. The sleeve extension adapter 26 is at least 2 /2 times aslong as the pin 18 and is shown in reduced diameter sections 28, 30extending axially from an upper sleeve section 32. If desired the sleeveextension adapter may be formed tapered with its smallest diameter endlowermost. The sleeve section 32 is formed with a cylindrical bore 34 ofa diameter and length such as to snugly receive the pin 18. Adjacent theupper open end of the sleeve section 32 there is provided transverselyaligned bolt receiving openings 35, 36. The upper end of the pin 18adjacent the boom 16 is also provided with a transverse bolt receivingopening.

In use the sleeve extension adapter .26 is fitted to the pin 18 by thereception of the pin Within the bore 34 of the sleeve section 32, and issecured to the pin 18 by the bolt 38 passing through the bolt openings35, 36 and the bolt opening in the pin. A nut 39 secures the bolt inplace. Thus, the sleeve extension adapter 26 may be moved bymanipualtion of the hydraulic controls into the axial sleeve or core ofa roll of printing paper that is standing on end on a floor surface, andby further manipulation of the hydraulic controls the sleeve extensionadapter 26 with pin 18 is moved towards the support carriage 14 so as tobring the roll of printing paper into a clamped seating engagement inthe cradle 20. Elevation of the support carriage 14 on the frame 12 willthen raise the roll of paper and permit transport thereof by the truck10 to another location.

The lift truck and its hydraulic rams and controls forms no part of thepresent invention which relates solely to the sleeve extension adapter26 and its application to the pin 18.

While certain novel features of my invention have been 3 shown anddescribed and are pointed out in the annexed claim, it will beunderstood that various omissions, substitutions and change in the formsand details of the device illustrated and in its operation can be madeby those skilled in the art Without departing from the spirit of theinvention.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. For use with a Bartell equipped lift truck for transporting a roll ofprinting paper having its central axial sleeve vertical, there being avertical pin carried by the truck for insertion into and engagement withsaid axial sleeve;

(21) An adapter comprising a rigid tapered bar element formed of aplurality of integral cylindrical sections of varying diameter havingthe larger diameter section providing the upper portion of the barelement and the smallest diameter section providing the lowermostportion of the bar element,

(b) a closed axial bore at the larger diameter end of said bar elementsnugly receiving said pin to locate the bar element in fixed coaxialrelationship with said pin so as to provide an extension thereof,

(c) aligned bolt receiving openings in said pin and larger diameter endof said bar element, and

(d) a bolt extending through said aligned bolt receiving openingsincluding a nut on the bolt for rigidly connecting the adapter to saidpin.
